Introduction
This document is the official product specification for the LSC043I08-R-V1, a 4.3-inch transmissive a-Si TFT-LCD module developed by LESSON Smart Display Technology Co., Ltd. Featuring a WVGA resolution of 480(RGB)×800, 16.7 million colors, an IPS panel, and driven by the HX8369A controller, this module offers exceptional flexibility by supporting both SPI (3-line serial) and RGB parallel interfaces. It is designed for prototyping, development, and products where the host microcontroller interface may vary or need to be optimized for pin count vs. performance.
